Apps Confused by a View!

[javano]

The scenario;

Main.java
[main calls otherclass with an intent]

Intent intent = new Intent(TestActivity.this, Otherclass.class);
startActivityForResult(intent, INT_INTENT);

Otherclass.java
[otherclass implements a Control and sets it as its view so I can capture input]

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Control = new Control(this);
setContentView(Control);
Control.requestFocus();

Control.java

public class Control extends View implements OnTouchListener {
.....//code goes here
}

How can I from Control (which is extended the view of otherclass) kill the otherclass intent and return back to mainclass. I have been capturing input so say a double tap on the control can trigger this event but I can't seems to get it right?

Under otherclass I had;

public void Back(){
Intent returnIntent = new Intent();
returnIntent.putExtra("value", "one");
setResult(RESULT_OK, returnIntent);
finish();
}

Which I called from Control with;

new Otherclass().Back();

But that doesn't do anything? (no errors, nothing?)

I also changed the Back() method to the following;

public void Back(){
    	setContentView(R.layout.main);
}

But that crashes my app?

I am clearly lost, what have I miss-understood here?
